Hi Ricardo. To post pictures, first re-size them to no larger than 800 x 600 pixels. Then, when posting, click the 'Go Advanced' button below the Message reply box. You'll see a window appear, with five boxes, in the 'Manage Attachments' field. Click the first box, and select the required image from your PC folders. Repeat as required, up to five times, then click 'Upload'. You can keep repeating this, five images at a time.
When finished, close the window and complete your post as normal.
Welcome to the forum, and I look forward to seeing your pics !
