I am using map tips to display geo-tagged images on QGIS 2.16.3, but I'm running into problems trying to control the overall size of the map tip pop-up frame.
I have followed the advice on other questions (e.g. Change size of frame for qgis map tip containing text) but it doesn't solve my problem...
This is what I'm using:
<div style="width:400;height:400"> [%CONCAT('<img src="D:/Photos/',"image",'" width="400"></img>')%] <p>[% "DESCR" %], [% "image" %]</p> </div>
This shows the photo, with text below. However, the 'div' doesn't expand beyond about 400px wide so it limits how large the photo can be displayed - the map tip window then shows scroll bars to view the 'overflow' image and text below (as it does if I set the image size larger than the div, as expected) - I haven't found any documentation suggesting there is a limit to the pop-up map tip, but maybe it exists somewhere?
Before anyone asks why I need a large map tip and it would use up lots of my screen, I know that - I have specific desire to see the images as large as I can rather than just a 'thumbnail', and map tips are a great way of introducing an extra dimension to the map.
As a related follow up (which I can post separately if that helps) - is it possible to change the x,y location of the map-tip pop-up. It looks like it appears below-right of the point that I hover - can it be centre-centre, for example. Obviously when I've got a large pop-up, it would be good to be able to see all of it!
I've also found that if I have another layer that uses a similar map tip, but without the 'div' statement within the same project, it displays as (approx) 100px high and 400px wide. Odd behaviour... I know I can get round that by setting a 'div', but that's not the point!
