Having a descriptive image filename is good for a number of reasons, but predominantly to help contribute to your websites SEO. To set the image filename:
- Right-click on your image > Web Properties
- Click on the Image tab
- Enter the Image Filename here
The best filenames are ones that describe what the image is about, or what is happening in the image. For example, take this image:
Now, you could just enter the word "beach", which is technically true! However this isn't very descriptive and doesn't separate this image from the other beach images. A better name would be 'seashore-sunset-beach', which is more descriptive of what is within the picture without overdoing it.
Hyphens are always more preferable to separate your words, however if you do enter a space it will be replaced with an underscore on export.
The file extension (.jpg / .png) is added automatically on export also, so you don't need to enter this.
Finally, if you enter the same name multiple times (which is common if you have a variant), Xara will stick an incremental number at the end to differentiate between them
