@raio The album names and image names are shortened on the gallery pages of albums and images and in the dropdown menu of the album selection popup on image uploads. This shortening of the names might be the problem. Can you tell me if the gallery pages of images and albums and the dropdown menu are the only places the problem occurs? Are the album names and images names respectively displayed correctly otherwise when not shortened? I would need to know to figure out a solution (as I don't think the fix you suggested makes sense).

@raio There is a change necessary in the code that shortens the album names / image names. In the files mod/tidypics/views/default/photos/selectalbum.php, mod/tidypics/views/default/object/image/summary.php and mod/tidypics/views/default/object/album/gallery.php you will find a line where the subst() function is used to shorten the titles. Instead of subst() the function mb_subst() needs to be used for the shortening to work without issues for utf characters (like cyriclic).

For example

$album_title = substr($album_title, 0, 17).'...';

has to be changed to

$album_title = mb_substr($album_title, 0, 17, "utf-8") . "...";

The corresponding change has to be made in all 3 files (with only a difference in the variable name used). Then the output should look fine.

@Rafael and Michael, I was having the same problem.  The fix I found was in line 45 has "$$plugin->im_path)" It has an extra "$".  It should be "$plugin->im_path)".  This fixed it for me.

how does one disable the download photo button ?

@marcnl: admin>settings>tidypics --> first tab, show download link -->uncheck that tickbox, this is a standard preference, have you checked the tidypics settings page in your admin?

i can upload profile images(avatars) and also it is stored in data directory like thumnails,small image... while installing (tidypics-preview) there is no error.

i can upload images no error while uploading, but uploaded images are not stored in data directory and no images in preview .

@kani: the Tidypics-preview version will not work anymore on recent versions of Elgg (>= 1.8.15). It fails to create the album folder in the data directory and therefore the images can't be saved. There is no error message about that but you might see a log entry about that in the server logs.

You would need to use http://community.elgg.org/plugins/1194049/1.8.1beta9/elgg-18-tidypics instead. This version of Tidypics fixed the album folder issue. If you currently have installed any other Tidypics version you need to first remove it (disable the plugin and remove the tidypics folder in the mod directory) before installing the alternative Tidypics version. Otherwise some outdated files could remain that might result in problems.

thanks a lot........great job
