This is so beneficial as it contains the essential core elements needed for collaboration between design, operations, and development teams in real work situations!! It would be amazing if you could create more core lectures like this that are needed for practical work!! This is a lecture that gives great strength to solo designers!! Highly recommend!!

I've had so many headaches with image issues in projects. I used to think image processing problems like processing and displaying images were simply development issues. After watching the lecture, the concepts are now crystal clear. Through the lecture, I clearly understood how to communicate with team members and how to design in projects. In particular, having example images for understanding with each explanation was fantastic. The video quality was so good that I could get a sense of what situation you were going to explain just by looking at the pictures. Thank you for the great lecture.

What you will gain after the course

  • You can understand the causes and consequences of image issues.

  • You can understand the image upload flow and take action in advance.

  • You can set the aspect ratio, resolution, and format to suit the service.

  • You can understand the structure where resizing is handled automatically by the server/CDN.

  • You can set separate image resolution criteria for each purpose.

You can prevent image issues from the start.

Image issues always arise too late in many products.

Aspect ratios don’t match, resolution gets distorted, loading is slow, and costs increase.

The main reason is usually the lack of an image policy.

This course teaches you strategies to prevent these problems before they occur.

user image upload settings, separating resolutions by purpose, aspect ratio and format settings, and more

Let's learn about it together step by step from now on.

Are you struggling with questions like these?

I recommend this course!


Troubled designer

'How many image areas should I use?'


Tired developer

'No more repetitive QA…!'


An anxious planner

'This will delay the schedule again…'

After completing the course,

✅ You can anticipate and prevent image issues that arise in real-world work in advance.

✅ Image standards become clear across planning, design, and development, reducing collaboration conflicts.

✅ You can control the quality of user-uploaded images, improving service stability and the user experience.

✅ You can reduce operational issues such as wasted traffic and loading delays to optimize service performance and costs.

✅ Designed to display images without distortion across various devices, strengthening multiplatform support.

    Image processing is quite a headache in development environments as well. Processing and handling images with code on the server or app side is quite troublesome. When image size issues are added on top of that, handling just that alone could take several days or more in the worst case. This lecture is not a technical lecture covering code-based processing, but it will help reduce the trial and error that can occur during development. This lecture does not cover technical content about image processing. It's more like a methodology for planning image sizes. This means the target audience is web designers or planners rather than developers. It's not a difficult or heavy lecture. It's fine to listen to it lightly during commuting hours. It's worth saving a cup or two of coffee. If it can reduce the cost of fighting between planning and development perspectives, it might even be considered more profitable.
