Hi @Barryt
Welcome to the forum! 
No…you are not the first to feel like that at the start…fear not!
Have a look at it from a different angle… 
Unlike other website building software, which offer pre-made components to drag and drop, but only limited control of customising them, Webflow instead takes that idea and gives you full control down to the div block and pixel, similar to being able to hand-code websites.
So, seeing it in that context, you could also say - is learning and writing HTML/CSS and JS mind-boggling if you’ve never used it before?
The answer to that is most likely yes, but stick at it a little and the pennies start to drop, push up over that initial mountain and then a world of capabilities awaits.
So yes, at first, with no training or familiarisation - creating something as simple as an image gallery is difficult to do, but only because you’ve got full design control of the pieces needed to create one. Webflow isn’t restricting your design skills, power is handed to you!
There are a number of great resources to tap into, and the forum here is very friendly - post away if you get stuck on anything 
- Which issue are you trying to solve with your current gallery?
