Login to Bongo4U Admin Mode and go to the page to which you want to make changes by clicking that page's link in the navigation or by using the "Pages..." option on the admin menu.
Supported image file types are .gif, .jpeg, .jpg, .png.
Click the "Block: WYSIWYG" link to edit your page's content. Determine the location on the page where you want the image inserted and click at that location (i.e. move your cursor to the insert location). Click the Image icon (a picture of a tree) from the WYSIWYG control panel to open the Image Manager in a new pop-up window.
(Note: If the Image Manager window does not open, then you probably have pop-ups disabled. Check for a message near the top of the page from your web browser and select the option that enables pop-ups from the current site (permanently) so that you can edit your WYSIWYG page content. Once enabled, you might need to click on the Image Manager (tree) icon again.)
Click the "Get Image" link. You will see the "Select or Upload Images" window. You will see a list of the images you have previously uploaded to your site. To link to one of these existing images, click the filename. To upload a new image, click the "Upload" tab near the top and follow the instructions under the "Upload" tab.
After you have uploaded and/or selected the desired image file, you will be returned to the first pop-up window (where the "Get Image" link is). Enter a short description (or Title) for this image (some users will see this text when they hover over the image, and search engines will use this text as well). Then click the [Insert] button near the bottom and your selected image will be added to your page at the insert location.
To insert another image, click at the insert location for the next image, click the Image Manager (tree) icon, click the "Get Image" link and do it again.
Once you are done inserting images, save the changes to your WYSISYG block by clicking the [Save Changes] button.
(Alternatively, if you wish to add an image using a separate block on the page (if you are not using the WYSIWYG block), then hover your mouse over the "Page" link which is located near the top of the page. The Page Menu will appear. Then hover over the "Add to This Page" option on the Page Menu and a sub-menu will appear. Click on the "Image" option on the sub-menu. This will add an Image block to the bottom of the page. If you wish to have an optional headline above this image, or an optional caption below the image, then enter them in the appropriate field. To upload the image from your local workstation, click the [Browse] button and then navigate/browse your local system until you find the desired image and click on it to upload. Once loaded, click the [Save Changes] button. To move the Image block to the desired location on the page, refer to the "How do a change the order of blocks on a page" entry.)
