When using crop and resize it should keep aspect ratio.

Please try to clean images\\artsexylightbox_tmp folder in case it contains old generated thumbnails.

Thanks for your reply - I don\'t actually have that folder..? The images are located in a folder I\'ve specified (images/gallery-courses). There\'s no folder called images\\artsexylightbox_tmp that I can find either in the root images folder or off of modules/mod_artsexylightbox/etc..

I tried copying my image folder, renaming it and using that as the new source but it doesn\'t make a difference. You can see the two variants (old and new image folder) on this page which is on a development area: http://www.marsbrook-1.info/index.php?option=com_content&view=article&id=34&Itemid=113

The two variants are one above the other.

Any other ideas fwhat I can try?

Ok, it looks like auto generate thumbs feature is not working for you: http://www.marsbrook-1.info/index.php?option=com_content&view=article&id=34&Itemid=113

Thumbnails are created from large images by resizing.

Is auto generate thumbs feature enabled? Do you have any PHP graphic extensions enabled on your server - like gd?

I do have generate thumbnails set to yes.

I have some fairly standard Joomla components, modules and plugins installed on the site, hence whilst it\'s always possible there\'s a conflict it seems unlikely. I don\'t have any php graphic extensions.

Later I\'ll try uninstalling and reinstalling it to see if that makes a difference.....I can always hope!

If you have any other ideas do let me know, & I\'ll feedback later on whether my efforts make a difference. [img size=220]http://www.artetics.com/images/fbfiles/images/options2.gif[/img]
