The problem with uploading pictures is that most modern phones and cameras have great resolution so the file size of the picture is too big for the web site.
Try this to get pictures uploaded- Right click on the picture file, go to "Send to," and choose "Mail recipient". It will automatically resize the picture for email. Once the email opens up you can right-click on the picture icon in the email and choose "Save as" to save it to a folder on your computer. This picture is then reformatted and ready to upload to the board. You can delete the email once you've saved the picture. No need to use another site or download a new program.
