Trouble with thumbnail sizes

Running Aveda Theme
Trouble I am having, please excuse my stupidity…
I have made no changes to my site in the last week as far as new plugins or updates. The only changes have been switching out photos on this page http://afurniturefind.com/sales/
For some reason in the admin panel when I upload the photo it is showing up like full size instead of the set 150×150 that thumbnails are supposed to. I did check the setting to be sure they were set and that the crop feature was checked. I did look in cPanel uploads to see what sizes are generating. I have about 5 of each photo per my theme but the 150×150 does in fact exist.
II have tried deactivating plugins one at a time and have not resolved the issue. Thanks for your assistance.
