4. Check the Exclude this picture from optimization.. option if you

don't want the image to be combined into one exported image if

overlapping with another image in your site.

5. (Optional) Choose from one of several resampling methods—

WebPlus can resample when needed, the file will always be resampled

(e.g., when a JPG is resized) or will never be resampled (original

image will be used). Enable the appropriate radio button as needed.

Changing the format will always resample.

6. To enter a title for a graphic, view the ALT and TITLE tab, and enter

the appropriate text. This is shown when hovering over an exported

image.

7. In the same tab, assign an ALT text string to your image for web

accessibility. The string is read out by screen reader on hover over.

You can assign text by entry into the input box or you can check Use

default ALT text instead. For the latter, the image is exported as

follows:

• If the images is decorative (contains no text) it will have no ALT

text.

• If the image is a clickable graphic such as a labeled button (e.g.

Back, Forward, etc.), text on the image is automatically taken,

exported as ALT text (i.e., Back, Forward) and presented to a

screen reader. If a title graphic is specified, the title text is used as

the ALT text.

8. Click OK.
