Google, Image Coast, and Photo Bucket.

The last often gives gals a hard time about erotic photos, so I wouldn't bother with them.

Imagecoast and photobucket are probably the most popular. Depending how your website is set up, you may be able to post pics directly from your website. (I know some ladies do this.)

Here is a list of hosting sites, copied from a several year old post. Some may no longerbe valid and theremay be some new hosting sites around now too.

I provided ample sized photos to a lady (2002 x 3000 pixels, 326 KB), but it appears on TER ad board as 233 x 349, 32 KB and ~ 2.5 x 3.5 inches.  

Is there a trick / better option for posting better / larger photos?
