standard licensing

Short answer: YES, a standard license is enough.

Long answer: License information and Terms of use | Adobe Stock .

The picture above is the resumé for the standard license. You can look into the link for more information.

You are publishing the asset on your website and you have "unlimited web views". You should, however, not publish the full resolution picture for 2 reasons:

• Saving bandwidth for you and your visitors.
• Protecting yourself against illegal downloading of the picture.
  
  You need to "protect" the image against illegal downloads, one "easy" possibility for this is not to publish the full resolution picture and if possible optimising for size (the picture should be highly compressed, but still good looking on modern screens). The good effect of a correctly downsized and re-compressed picture is to make the picture less usable for reworking.
  
  You will have still access to the full resolution picture, so if you need the picture for a printed catalogue, you can use it for that, even with your standard license, given that the print run (combined over the "lifetime" of use of the picture) does not exceed those 500k copies.
