With windows I just go to advance posting, click on Manage Attachments in Attach Files box. It opens a new window so I can select my photo(s), I click on Select Photo, it opens my photo save file, I click on the photo I want, click on Open and it loads. If you want to add more then one photo you do it at in the same window. If the photos is in a different file you go back to you main photo save file and go to the next photo you want. You can load up to 7 photos. Close that window and you should see the file listed in the Attach Files box. Click on Preview Post and you should see the photo, then click Submit Reply. Hope that helps.
