Disable link to flickr on single photos

i think this link negatively affects to website SEO.

That is definitely not true. An external link has zero impact on your SEO, unless you are building a link farm.

As per the Terms of Service for Flickr when Photonic was built, an application built for Flickr was supposed to provide a link back to Flickr. I don’t know if the TOS have changed, but the reason I have the link in there is to prevent myself from legal implications.

One suggestion though: you only seem to be displaying a single photo from Flickr and nothing else. Why would you need a plugin for this? Typically you would use something like Photonic if you want to display the associated caption etc. and automatically link back to Flickr. For everything else using a plugin is an overkill. When you are using a plugin for this:

1. Behind the scenes the plugin is first executing the shortcode / block.
2. Then it is making a web-service call to Flickr – this takes processing time.
3. Then it is using the results of the call and generating the markup, which it is passing to the front-end
4. Then the front-end is pulling the image from Flickr to show to an end-user.

If you are only interested in displaying a photo (and you don’t want the caption and a link to Flickr), why not use a simple <img> tag? That eliminates all the heavy processing by the plugin and directly jumps to the last step of the plugin flow above.

Using an <img> tag is as simple as just defining something like this:
<img src="https://farm66.staticflickr.com/65535/50691388986_233da0a0a2_z.jpg" alt="Varsana-Truly-1024x682">

Hi, i used your plugin because i also need to insert flickr galleries in my website, anywhere i will use img tag like you advise to me.
Thanks

Ah, I see. That makes sense.
