yes, I understand that and I agree with you, the problem I have is that I don’t get only 3 different sizes, I get 12 sizes uploaded in one blog and 7 on the other one. Is a lot of unnecessary files that occupied inodes of my plan. I really would like to know if it is possible to delete them somehow. In the media settings it doesn’t give me any information about all this sizes:
140×170
140×94
150×150
184×184
207×136
212×213
260×170
260×315
300×160
430×283
430×320
500×320
