I have two WordPress blogs in the same hosting package.
When uploading an image, WordPress uploads it in many different sizes, 7 in total but I only use the full-image size. The problem is I usually write posts where I upload many images. For example, the last post I wrote included 27. If multiplied by 7 I get a total of 189 files uploaded to my server instead of 27. If I multiply by 7 every time I post something I get many pictures uploaded that I'm not using.
I use Dreamweaver and I'm able to erase the images I don't use via ftp. The problem is I'm afraid of doing this because I don't know if they are needed somehow. I suppose they don't but I really would like to be completely sure before deleting anything.
Additionally, is there any way using the preferences panel of setting how many images I want to be uploaded? for example just the full size one?
Thanks in advance for your help,
