gives HTTP error 500 (Internal Server Error) to search engines ., search engines(google) cannot crawl the page , on browser every thing seems to be ok. but to crawl by search engine.

the Automatic Thumbnail patch had as a side effect the adding of frames to the logo and images to the web catalog.
This file fixes them.
If you allready have a edited html_output.php file compare the one posted here to the original non moddified one from the web, and apply the differences to yours.

Hi everyone,
Last code present a bug when a thumb has been generated. colorimetry was upset so it could not be possible to use the thumbnail.

So I took a older code and I just add quality option as in last ones !

know it works good.

Bye

i think this is a bug. anyone whos got problems try this and see if the pictures show up.

WARNING

this contribution messes up OSC in unexpected ways.
all pages displaying thumbnails will generate a HTTP error 500 (Internal Server Error) on machines running the latest PHP (5.2.4)
you won't get the error in a browser, but all robots will be snubbed.
test before using!

I have 4 different OS sites. I have tried this on all 4 but each time it crashes with an error message on one or more images.

Seems the code is set to DIE if an error occurs rather than default to the standard image handler.

I've looked at the code but I can't see the fault. It either says (in german) "Image doesn't exist" or it says that one of the dimensions is set wrong (both of which aren't the case).

(Attached is the version I'm using)

I have spent the last 3 days looking for the alternate feature of thumbnailer, It removes the image not found box in New Products. By just installing this beautiful package you will no longer have the image not found on your New product boxes anymore. This is important for those that have broken images that work with large databases and don't want to manualy remove broken links. Thanks to saving the Day...

Change

$subdir_consola = $subdirectorio[1] . '/';

for

$subdir_consola = str_replace('images/', '', dirname($src)) . '/';

Now you have unlimited subdirectory support!

This file fixes the bug of the html_output.php file

So replace the old file.

Enjoy : now the cache file is efficiently created in the catalog/images/thumbs_cache/ directory

:-)

This is an Add-On to the contrib "Automatic Thumbnail"
http://www.oscommerce.com/community/contributions,1484/category,all/search,thumbnail
I used the version of date 11 Jul 2006, uploaded by: olaf_noehring

My products images are in different subdirectories depending on the categorie of the product, for example:

catalog/images/videogames
catalog/images/computers
catalog/images/pets
catalog/images/randomstuff

and normally the Thumbnail generator will save all the thumbs created to
catalog/images/imagecache

with this mod the thumbnails will be saved this way:

catalog/images/videogames/thumbs
catalog/images/computers/thumbs
catalog/images/pets/thumbs
catalog/images/randomstuff/thumbs

So this way you have your thumbs organized in the correspondent directory.

This only work with images saved in the catalog/images directory or images saved to the firs next subdirectory like catalog/images/subdirectory

It will not work in directorys like: images/subdirectory/anothersubdirectory/

Most people only need the first directory, my php skills are limited and i only needed 1 subdirectory. But it should be easy to make this work with more subdirectories.

THIS IS NOT THE COMPLETE CONTRIB, ONLY THE INSTRUCTIONS TO ADD THIS MOD.

Sorry for my bad english..

Hi

I extended the previous version just a little to make it possible to set the image quality of created jpg thumbnails.

If you have installed already, update instructions are included.

Update/Installation takes not more than 3 minutes I think.
1 file to change

Added support for caching of multiple thumbnails sizes from the same source image, by adding dimensions of cached image to the cache image filename.

Changed line from:

$thumbfile = '/' . basename($image);

to:

$thumbfile = '/'.$x.'x'.$y.'_'. basename($image);

Removal of GIF from 'not supported' parameters to allow gif thumbing.

The only update to this version is 2 lines of code added to the thumbimage function.

Now it will check the original image and see if it has been modified. If so than it will re-cache that image.

To upgrade your existing code simply open
includes/functions/html_output.php

and add
------------------------

if (@filemtime($cachedir.$thumbfile) < @filemtime($image))
$iscached = false;

after
-----------------------
if (file_exists ($cachedir.$thumbfile)) {
$thumbdata = getimagesize ($cachedir.$thumbfile);
$thumbdata[0] == $x && $thumbdata[1] == $y
? $iscached = true
: $iscached = false;

After struggling with trying to get my thumbnails small all morning I have download this contribution and had to change some code to make this work right away with older versions of GD, I'm running 1.6.2 on PHP version 4.1.2 and it works just fine as far as I can tell.

Best of luck, this is my first post on here and hopefully not the last.

This is a simple modification that will also delete the generated thumbnail image from the imagecache dir.

Links don't work in this field, so here is the link to the topic in the forum:

The download File is the same as in my last entry.

I updated the script with the update from Lars Iwer listed below (Thank you Lars!!) and the lines listet in the <a tartget="_blank" href="">forum</a>.
So use this download and you have the "newest" version.

in order to work with gdlib versions < 2.0 (i.e. 1&1 still has an old gdlib installed) you should replace the lines

$thumb = imagecreatetruecolor ($x, $y);
imagecopyresampled ($thumb, $image, 0, 0, 0, 0, $x, $y, $imagedata[0], $imagedata[1]);

within the function thumbimage() with

if (function_exists("imagecreatetruecolor") && ($thumb = imagecreatetruecolor ($x, $y))) {
imagecopyresampled ($thumb, $image, 0, 0, 0, 0, $x, $y, $imagedata[0], $imagedata[1]);
} else {
$thumb = imagecreate ($x, $y);
imagecopyresized ($thumb, $image, 0, 0, 0, 0, $x, $y, $imagedata[0], $imagedata[1]);
}

updated installation instructions added

This is an automatic Thumbnail creator.

Each picture in your Shop will be chached in the "/catalog/images/imagecache" directory in the right
size and with the same name as the original.
The size is set in the Admin panel under Configuration - Images.
These values are the max values. The thumbnail will be created in the right proportions.

The tumbnail will be created an th first time the picture is call in the Shop.
Once an thumbnail is created it will always be used until you change the size in the Admin panel.

If you delete an image, you have also to delete the thumbnail in the "/catalog/images/imagecache" directory manually

Have fun!


Installing should be quite easy, only one file tho change.
