Image Manager addon

[tandbparties]

Have vs 1.9 installed (ZenCart 1.5 store) and all works well but I have no "Delete File" option for resized Large images. I do notice that the Large image dimensions remain in red even after correctly resizing and Medium images (with delete option) are in black. Any ideas on why I have no Delete option for my Large images?

I think I've got this working with the additions of:

$images[$image]["large"]["delete_link"] = ($dirread[DIR_FS_CATALOG_IMAGES . "large/" . $p["dirname"]] == true && IMFileIsWriteable($filename_large) ? $partlink. "&actcnt=" . ($_SESSION["actcnt"] + 1) . "&IMaction=deletefile&filename=" . urlencode('large/' . $p["dirname"] . $p["filename"] . IMAGE_SUFFIX_LARGE . "." . $p["extension"]) . "\" onclick=\"return confirm('" . IM_CONFIRM_SINGLE_DELETE . "');\" />". IM_IMAGE_DELETE . "</a>" : "");

at line 358 of the function_image_manager.php file.

Please let me know if this is an acceptable solution or if this will cause other problems?

OK, just needed to get one of my original images with the txt extension, and changing it back to a jpg corrupted the image. Seems to happen with every transition from txt to jpg extension, but did not happen with the former bak extension. Is there a safe way to convert the txt back to a jpg, or is the change to a txt file for backup just always going to result in a corrupt image?
