General Image question regarding search results

[theremotedr]

Currently its shown as

<a href="javascript:" onclick="replaceMainImage('m-images/photos/FIAT004.png', 'Fiat004','<b>£35.00</b>

By adding a ALT tag it would then be shown as
<a href="javascript:" onclick="replaceMainImage('m-images/photos/FIAT004.png alt="Fiat 1 Button Key', 'Fiat004','<b>£35.00</b>

And scripts etc would be untouched,just making sure this is the correct way in adding the extra alt section before i start ?

Thanks

It isn't an img tag so Google will have a hard time making the association, if at all. Google will not click your link, parse the JavaScript, run the function, build the markup and then interpret it as a dynamic image on the fly. For Google to read and understand an img from markup, it needs to see an <img> element in the markup (HTML not JavaScript).

Ok
So im a little confused but understand what you are saying,i understand the link will not be clicked hence why im asking where i need to make the edit.
If currently i have an image named FIAT004
And the code on the page for it is as follows.

<li><a href="javascript:" onclick="replaceMainImage('m-images/photos/FIAT004.png', 'Fiat004','<b>£35.00</b><br>Chip Will Require Programming<br>Key Will Require Cutting<br><scan class=keychipColor>+ Virgin Chip & Uncut Key</scan><br><b>UK Recorded £2.50</b><br><b>International Signed For £10.00<br></b><b>Posted From The UK</b><br><scan class=drColor>The Remote Doctor</scan>')">One button key remote</a></li>

Please advise what/where i need to edit etc so i can continue with this.

There is no benefit in adding an alt attribute on the client-side via JavaScript - Google will not see it in the context of an <img> tag. You will be better off focusing your energies on making changes that Google can see and understand, such as rename files with descriptive keywords.

Ok
Tomorrow i will start to rename all images.
I will keep the initial file name Fiat004 etc but add extra text.
Is Fiat004 one button key ok or should i add fiat again like so ?

Fiat004 Fiat one button key

The whole point of doing this is for search engines etc so dont want to do it twice .

Many thanks again.

Hmmm, this isn't a great idea because it will have a negative impact on page performance - All the images will download in the background, even though they will not be seen.

Yes, I agree that it will slow down the page loading marginally. However, it will achieve what the OP asked for with very little intervention in the source code.

Not necessarily. Gary Illyes from Google stated this a similar online discussion in late-July 2015;

Hiding the content with a display:none might backfire on you. We are giving hidden content way less weight in ranking.

theremotedr - if it were me I'd name them 'fiat004-fiat-one-button-key.jpg' so you still get the benefit of your part number for organisation purposes in the backend.

[theremotedr]

So do you advise me to do this.

Please refer to my previous post regarding suggested naming convention.
