Missing images in version 2.5.1

[facultymatt]

Hello, I'm experiencing an issue where images are missing, heres what happens:

• Images upload from lightspeed fine. I see them sitting on server.
• When i visit a page for the first time, the image is broken . I get the following php_error_log: image.error : Failed to save file product/1/1950s-crew-sweatshirt-512px-445px.jpg PHP Fatal error: Call to a member function ShowThumb() on a non-object in /var/www/vhosts/trovegeneral.com/httpdocs/includes/data_classes/Images.class.php on line 316
• The image is now deleted from my photos collection. Im guessing it deletes the original when it successfully creates the resized version, however in this case its failing and deleting anyway.
• Next time I visit the page, images appear as default not found image.

Any thoughts as to whats happening here? Whats especially odd is everything seemed to be working fine until recently... not sure what changed. A store reset and product upload maybe? Would a config setting be causing this failure?

To debug, I have also replaced the store with a fresh DL of the 2.5.1 branch - this error stil occurs. Is this a known issue in this version?

Thanks in advance, -Matt

Interestingly the small thumbnails on the product page save fine, ie: 1950s-crew-sweatshirt-add-1-135px-165px.jpg... it's the category and detail page images that fail.

Also, the original image is 512px x 424px... but the system is trying to upscale to 512 x 445, would this cause failure?

I've actually pinpointed this issue. If DETAIL_IMAGE_WIDTH === image width then the resize function fails. For example my original image is 512px wide x 424px tall. If I set DETAIL_IMAGE_WIDTH = 512 in the appearance panel, the image fails. If its 513 or 511 everything works fine. @note that DETAIL_IMAGE_HEIGHT doesn't seem to have the same issue.
