Streach and cutting Edges are good options... i would really like if both were there and user could choose it...
User can choose it? Did not even think about that
The version that I will be releasing will only be a global selection for the entire site. In order to allow the user to select, I will have to completely redo the code but may give it a try down the road.
The only issue I see is that allong with the original file you would then have a
resized_1024X768 file
resized_stretched_1024X768 file
resized_copped_1024X768 file
for each of the sizes that the user could choose, may get confusing on a large site but doable. at least the extra files would be in a big subfolder, easy to delete if running out of space.
If enough people think this would be a good addition I may work on it harder...
