Hi pirondubois and a warm welcome to you from all the Staff and Moderators.
To get your birds identified, start a thread in the
ID forum. To upload your pictures, first make sure they're no more than 1600 pixels on the longest side. Save a copy to your desktop. This is for jpgs, it varies for other formats, which are shown on the pop-up screen.
To upload the pictures in a thread, make sure you're in an advanced posting mode, either by starting a new thread, or by clicking on Post Reply (if you're in Quick Reply, click on Go Advanced).
After you've typed your comment, scroll down below the message pane and you will see a grey Manage Attachments button.
Click on that and then Browse for your first picture and double click on it. Click on Upload and wait a few seconds until you see the filename appear in the box.
You can do this 4 more times for each post (the maximum is 5 pictures per post, but there is no limit in the thread).
Close the box.
You can check the pictures are there if you click on Preview.
When you submit your post the pictures should appear at the bottom.
Do come back if you need more assistance.
