I agree 100% with Doug.
The most common size for pbase is a maximum of 800 pixels wide, so you only have a small, medium & original size. 800 max gives a nice size for most screen resolutions, and isn't so large they can be made into large size prints.
It's best to use "Save As" function if using PS, so you're exif is kept in tact so others can view it. Using "Save for the Web" removes it. Also, a good size is between 125 & 200 kb when saving, going lower tends to add artifacts which makes for less than best quality. Note too, that using the "Save As" function allows you to rename your shot as a copy (or different name for easy finding) and doesn't destroy your original. This is suggested in case you later need the larger files for printing.
DPI isn't something to be too concerned over, I believe most programs default to around 72, and really doesn't affect viewing on the web anyway if I understand right. More important things as color space would be something to watch. If you save in Abode RGB instead of sRGB it's going to be converted when uploaded. This will result in color change, and other possible degrading.
