Disha,
If you have your photos, of your lace, stored on your computer, all you need to do is to go to the top of the first message and click the 'reply' button up there. Do NOT click on 'quick reply'.
Once you click on the REPLY at the top of the page, it will take you to another page for posting. You can click on an image to post an emoticon OR in the section where you type your reply you will see where you have some buttons for BOLD, UNDERLINE, FONT, etc. There is also a button where you can insert an image, but you must know the URL for that image in order to insert it.
Our forums are being updated, so maybe one day we'll be able to upload directly from our computers.
