Întrebări frecvente

-or possibly frequently asked…

Why did you make this plugin when there are so many others to chose from?

Good question! Being a photo enthusiast having a WordPress site with one post per image, I realized after a while that there were limited possibilities to show the images in a smooth flow.

To avoid the cumbersome manual navigation between posts, I decided to (try to) write a plugin to collect the image from each post, show them in an image slider and then navigate to the post from the image. The content of the slider is then defined based on the context of the page, for intance an archive page that contain the result of a tag query.

Messing around with various gallery plugins – that always require som extra effort to set up – or modifying page template code was not an option.

Eventually the plugin was extended to be applied for general use as well, and the handling of one-post-per-image has just become an optional feature that can be turned on/off from the plugin settings page.

Are there any shortcut keys available?

Yes, for those users who are blessed with a keyboard:

right arrow/left arrow – next/previous
C – toggle caption if supported
A or P – toggle autoplay
B – switch background class
L – last image
T – swith between slide in/out or cross-fade transition
V or S – switch view style
X – exit
Z – zoom mode on/off

Which touch gesture or mouse operations are supported?

swipe left/right go to next/previous image
spipe up/down exit viewer
pinch – zoom
doubleclick/doubletap – enter/exit zoom mode
left mouse button down while swiping right/left with mouse – next/previous
ctrl key and left mouse button down while swiping up/down – enter zoom mode and do zooming
mousewheel – zoom when in zoom mode
click caption – turn off display of caption if captions are supported. Turn it on again from menu.

Only one image from a gallery or carousel is shown, and no arrows – why?

Probably due to that the the gallery or carousel wrapper is not detected. Please specify the parent element to all the gallery or carousel elements. If in doubt, do not hesitate to file a support ticket.

Can I choose which posts/pages and images it shall be activated for?

Yes. This can be specified in the plugin settings page.

Can I modify the styles?

Yes. Please have a look into the plugin settings page and the stylesheet located in the plugin directory. If you need advice on how to set up the styles, please leave a support message.

Is it responsive and touch-device friendly?

Yes, I think so.

I do not see any menu when accessing from a touch device

That’s right, it was made like this for simplification. The menu can anway be accessed by a long-press, and it will appear as context menu.
Please submit a message in the support section if you think it should be different.

Does it work in all versions of all browsers?

Most likely not, but it seem to work as expected in ‘all modern browsers’. There may be several ways of marking up a page so there could be situations when some tuning is necessary. Please leave a message in the support section if it does not work as expected.

I needed a way to render images of varied original quality (historical records scanned by a third party) so users could clearly focus on text and read. I tried numerous lightbox, gallery, photo plugins and none accomplished this - magnification / zooming was too limited or resulted in image distortion or loss of responsiveness. What I really wanted was flexible magnification and panning while maintaining clarity and responsiveness. Image Projector does exactly this and doesn't come with excess features/bloat. When I look for a plugin I read the reviews, I look at whether or not it's being maintained. Ordinarily, I might have overlooked this one given its age and low number of downloads, but it had been recently updated and was a great fit for my needs. After installing, it didn't work. Typically, I walk away and simply use something else, but I'd already tried the other options. This time, I went to the support forum. And viola! I have an updated version (5.3) installed and all is great! So, a huge applause for the developer who was responsive and expedient with the needed fix. It is completely compatible with WordPress 6.2.2 and twenty twenty-three. Image Projector is the best I have come across for responsive detailed image viewing with just the right number of customizing options!

This plugin is a good choice if you use DIVI, and want using alternative lightbox. With this plugin can zoom image in lightbox, bright/dark background, lot of control settings, caption support and many more good options. And the support is excellent. I really recommend it.

The possibility to choose background; white/dark is so brilliant. Also you can choose different sizes to show your photo in the lightbox + more options. And as a quick respond to my request they added a choice to limit the image to original size. So -the support is also excellent! A very nice and unique plugin indeed. Recommended.
