I have an issue where I want to use square pictures in the Thumbnail view – in some cases this means that it needs to use the cropped version. However, in order to get the cropped square version, I have to use the ‘Thumbnail’ setting in the Gallery Size Option/Thumbs Options tab. This uses the resized 150px by 150px version of the file which is too low resolution for the purposes. You can see an example of this here. If I use the medium/large or full setting I end up with a full frame version of the image with a yellow background as you see here). This is not what I want to achieve. Is there a way of forcing the code to use the automatically generated ‘-320x320_c’ version of the file?

In the actual site I have created larger res versions of the 150×150 files (they are actually 300×300) and uploaded them using the same name. It us not a very satisfactory solution as it means that my client cannot upload the images herself and it takes a long time for me to do as I have ensure that the formatting is the same as the existing filenames (i.e. no spaces or symbols and precisely the same extension.
