Uploading help please

[QueenBee]

I uploaded a picture to the Scrapped Contest album for May, but ,,,,,
It is so tiny. I had to keep reducing it in order for it to finally upload at all, and now you can hardly make it out!! I am using my PSE8 resizing but I am really a novice and can't seem to figure it out.
can anyone help me get a larger sized picture while keeping the file size down to the maximum allowed
Thanks a bunch
Lynne
