Help! Get id of tag <IMG>

sorry for dummy question, but I’m a newbie.

I’ve a html page with contains lot of images with different id:
<.IMG src=“image_link” id=“image_number_1”>
<.IMG src=“image_link” id=“image_number_2”>
<.IMG src=“image_link” id=“image_number_3”>
<.IMG src=“image_link” id=“image_number_4”>

I would access the img tag and store the id in a variable (possibly only the substring “number_X”).

How can I do this?

Thank you very much

Hi, thank you for your reply. Probably I was not too clear in my request…
<.IMG src=“image_link1” id=“number_1”>
<.IMG src=“image_link2” id=“number_2”>
<.IMG src=“image_link3” id=“number_3”>
<.IMG src=“image_link4” id=“number_4”>

I need to access code with a specific SRC and I need to get the ID and store this information to be used in next step.

For example: I need to retrieve the ID of image with src=“image_link3”. Result should be a variable sotred with text numebr_3 (or possibly only number 3 as substring of id text)

Thank you and regards
