Update: refer to Failsafe way to make photo uploaded via Blogger unclickable
This is a rare question as most have problems where they found their photos not clickable and want to know why plus the solution.
One reason put forth is when you upload your photos in the Blogger post editor COMPOSE and then drag-drop them to shift them around (something which I hate to do), the photos may become unclickable. However I myself have not tried it myself as I hate to use the COMPOSE mode and sort of "boycott" it, today I tested it at testing if drag-drop images to move it while in the COMPOSE mode of the Blogger post editor window will make images unclickable and found that even after dragging and dropping the photo in the COMPOSE mode to move it, that photo was still clikable. However, read what else was written in the post as other bloggers had reported conflicting results.
I further tested displaying a photo using the <img> tag in testing if using the HTML image tag will make the image unclickable and the result was that I can make it unclickable.
How to make image unclickableThis is what you need to do. Do not upload your images direct via the Blogger post editor window tool bar. Upload it to some image (photo) hosts like the free Photobucket image host. Get the image URL, then use this image HTML tag to display the image:
<"img src="image URL" />
If you want, you may want to add some useful attributes lie alt="some text to tell search engines what the photo is about" and/or title="some text which will be shown in a tool tip when the mouse cursor is hover over them image. To make it clear, I will paste the actual script I used to display that unclickable photo in HTML image tag to make displayed images unclicable:
Please be warned that I can make the image clickable if I want even when using the <img> tag and if you want to know how, you will have to ask.
