If you have a Redback Graphics installed CMS website
To add an image to an existing pre-installed gallery (with navigation/scrolling thumbs and arrows on the page)
Login to your Dashboard, under “Dashboard”, click once on “Media”, then near “Media Library”, click once on “Add New” button. Choose “Select Files”, locate them on your computer, select the file (or multiple files), select “Open” (or hit enter), wait while it “Crunches” the file/s (uploads). At this point you can (not necessary) edit Titles, description, captions etc. This can be done at any time, so no need to do it right now. Then click “Save all changes”. You will then be back in Media and can see a list of the images now in your Media collection.
Any image/s you just uploaded (you can upload several images at a time) will not be “Attached” to any particular page. In order for them to appear in a gallery on “a” page, they must be “attached” to that page. Check the select box for all images you want to “attach” to a particular page, then click “attach” for one of those images (all images with a check/tick will ALL be attached to the same page that you now select). In the “Find posts or pages” box, type a few characters of the page name you are looking for, then select “Pages” and “Search” to locate the correct page you wish to attach those images to. Select that page, and you are done. The image will now be added to the existing gallery on that page.
To add an image to a normal gallery (no navigation/scrolling thumbs and arrows on the page, just thumbnails)
Login to your “Dashboard”, click once on “Pages”, then once on the page your gallery is on.
If you see a large blue box, click it once, then the “Edit Gallery” icon. Click “Add to Gallery” button, find or “upload” the files to add, select the files, then update the gallery, and update the page.
If you see small thumbnails on the page in a grid, position the cursor where you want the new image, choose “Add media” or “Add/insert image”. Find the image and choose link, “Link to file” and size, “Thumbnail” and insert into Post. Update your page.
It’s always handy to have another browser window open to view the “public” side of your website to see the changes without having to log in and out of your Dashboard to see the public website. The changes will be live immediately. Use CTRL+F5 in your live website browser window to force a refresh of the web page you are viewing to see the updated image and link.
Always backup your website before doing any updates until you are very familiar with updating pages and images etc.

Adding descriptive Titles to your images will greatly increase your SEO (Search Engine Optimisation). If you name your images with an exact string that you might expect someone to “Google”, your image (and your website) will then rank highly in any Google results. Making the Title specific, but also unique will give excellent results. For example, if you were to name an image “twitter free zone”, then anyone Googling twitter free zone would quickly find your website. Your challenge is to predict what people be Googling (exact string), then include an image you can name accordingly. The more correctly named images you have, the higher the Google ranking for those strings will be. Do NOT try and trick Google by adding excessive images with blatant SEO Titles, Google will recognise that and blacklist your website completely. Just include relevant content, with relevant images with descriptive titles, and Google will love you, and people will find you.
